从文件读取和写入

Question

我想用c ++编写一个程序,它提示用户输入一个包含10条记录的现有文件的文件名,每条记录的长度为12个字符.接下来,程序寻找第6条记录的开头,读取文件中的记录并将它们附加到包含3条记录的现有输出文件的末尾.谢谢.

您可能会发现这很有用:

#include <iostream>
#include "McDonaldsApplication.h" 

int main()
{
  McDonaldsApplication app;
  string name, dob, pos, ssn;
  std::cout << "Enter your name: " << std::endl;
  std::cin >> name;
  std::cout << "Enter your DOB: " << std::endl;
  std::cin >> dob;
  std::cout << "Enter your SSN: "  << std::endl;
  std::cin >> ssn;
  std::cout << "Enter your desired position (0,1,2): " << std::endl;
  std::cin >> pos;
  std::cout << "Thank you! Your application is being submitted now\n";
  app.setName(name);
  app.setDob(dob);
  app.setSsn(ssn);
  app.setPos(pos);
  app.submit();
}
